Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman Numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman Numerals, rules, and examples.
The royal titles, such as Henry V, Henry VI, and so on. Have you noticed the names and wondered what these symbols (V and VI) represented? Those are the Roman Numerals.
Earlier people used to count using fingers, sticks, bones, etc., to count. When life became complex, a standard form was required to count. Ancient Romans used the Roman Numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.
In Roman Numerals, we use DXXVI to represent 526, where D is 500, XX is 20, and VI is 6. Let’s learn more about Roman numerals and how we write them.
There are certain basic rules to write a number in Roman Numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals.
The addition method is used when the smaller number is placed after the larger number. For example, VI → V + I → 5 + 1 = 6.
To write a large number, there are certain Roman Numerals that can be repeated three times. III → 3.
If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, IX → X - I → 10 - 1 = 9.
The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we won't write VV for 10; instead, we use X, and 8 is written as VIII, not IIIIIIII.
Let’s now learn how to write 526 in Roman Numerals. Follow these methods to write the number in Roman Numerals.
In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 526 in Roman numerals using the expansion method.
To write 526 in Roman Numerals, follow the steps:
Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 526, we write it as 500 + 20 + 6.
Step 2: Convert the number into Roman Numerals.
500 in Roman Numeral - D
20 in Roman Numeral - XX
6 in Roman Numeral - VI
Step 3: Combine the Roman Numerals together. Therefore, 526 in Roman Numeral is D (500) + XX (20) + VI (6) = DXXVI.
When writing a large number in Roman Numerals, we group the number. To write 526 in Roman Numeral, we group 526 as 500 + 20 + 6.
So, 526 is written as DXXVI in Roman Numerals.
Students make mistakes when writing a number in Roman Numerals. To master Roman Numerals, we can learn a few common mistakes and the ways to avoid them.
A historian finds a manuscript stating a king ruled for DXXVI years and another ruled for C years less. How long did the second king rule?
The second king ruled for CDXXVI years.
The second king ruled C years less than DXXVI.
DXXVI = 526
C = 100
526 - 100 = 426
426 in Roman numerals is CDXXVI.
An archaeologist discovers DXXVI artifacts in a site and wants to distribute them equally among XIII museums. How many artifacts does each museum get?
Each museum gets XLV artifacts.
To find how many artifacts each museum gets, divide DXXVI by XIII.
DXXVI = 526
XIII = 13
526 / 13 = 45
45 in Roman numerals is XLV.
Calculate the sum of DXXVI and LXXIV.
The sum of DXXVI and LXXIV is DC.
Sum is the result of adding two numbers.
DXXVI = 526
LXXIV = 74 526 + 74 = 600
600 in Roman numerals is DC.
The sum of DXXVI and LXXIV is DC.
What is the difference between DXXVI and CCCXXVI?
The difference between DXXVI and CCCXXVI is CC.
The difference is the value obtained by subtracting one number from another.
DXXVI = 526
CCCXXVI = 326
526 - 326 = 200
200 in Roman numerals is CC.
Express the sum of DXXVI and CCLXIV using the expansion method in Roman numerals.
The sum of DXXVI and CCLXIV is DCCCXC.
Step 1: Convert the numbers 526 and 264 into Roman numerals:
526 = DXXVI
264 = CCLXIV
Step 2: Add the numbers:
526 + 264 = 790
Step 3: Use the expansion method:
790 = 700 + 90 = DCCC + XC = DCCCXC.
